City-size comet racing toward Earth regrows 'horns' after massive volcanic eruption

An enormous volcanic comet the size of a small city has violently exploded for the second time in four months as it hurtles toward the sun. And just like the previous eruption, the cloud of ice and gas emitted what looked like a gigantic pair of horns. The comet, named...

Scientists may finally know where the biggest, oldest black holes in the universe came from

How do you build a giant black hole in the early universe? Start with the explosions of lots of little ones, a counterintuitive new preprint study proposes. Numerous observations, especially with the James Webb Space Telescope (JWST), have revealed ironclad evidence that the young universe was populated by incredibly massive...

An explosive, green comet racing toward Earth is currently zooming past the nearby Andromeda galaxy in the night sky, setting the stage for some stunning photographs. You can also watch the comet fly past our spiralling galactic neighbor in real time, thanks to an upcoming livestream. Comet 12P/Pons Brooks (12P),...

See green comet Nishimura's tail get whipped away by powerful solar storm as it slingshots around the sun

The recently discovered green comet Nishimura has been body slammed by a potential coronal mass ejection (CME) after surviving a close encounter with the sun. The unexpected collision, which briefly blew away the comet's tail, was caught on camera by a NASA spacecraft. In footage captured by NASA's Solar Terrestrial...

Green comet Nishimura survives its superheated slingshot around the sun. Will we get another chance to see it?

A recently discovered green comet, named Nishimura, has survived its close encounter with the sun and begun its journey back into the outer reaches of the solar system. Once gone, it won't return for around 430 years. But it could be visible over the next few weeks, depending on where...

Volcanic 'devil comet' racing toward Earth resprouts its horns after erupting again

A volcanic devil comet that is racing toward Earth erupted again on Halloween, causing it to regrow its distinctive horns. The latest outburst, which was the second within a month and the third since July, is a reminder that the comet is becoming more volcanically active as it continues its...

Explosive, green 'devil comet' photobombs ethereal nebula as it races toward Earth

Stunning new photos show the volcanic devil comet zooming in front of a striking crimson nebula as it races toward Earth. The green-colored comet, which is long overdue for another eruption, will make its closest approach to our planet later this year. The explosive icy object, named Comet 12P/Pons–Brooks (12P),...

City-size 'devil comet' headed for Earth loses its iconic horns and turns green after latest volcanic eruption

The massive volcanic devil comet, that is racing toward the sun may have lost the distinctive horns that earned it its sinister nickname. Last week, after the comet's latest and most violent outburst yet, its trademark head spikes did not appear as they did after previous eruptions. But astronomers have...

Halley's Comet has begun its return journey to Earth

After zooming away from Earth for nearly 40 years, Halley's Comet has finally turned tail and started heading back our way — setting the stage for a spectacular close-up in 2061. On Saturday, Dec. 9, the famous comet was predicted to reach its farthest point from the sun, also known...

The James Webb telescope may have found some of the very 1st stars in the universe

Evidence for the first generation of stars to exist in the universe has come to light, thanks to observations made by the James Webb Space Telescope (JWST). The proof is located in one of the most distant galaxies known. The galaxy, designated GN-z11, was discovered by the Hubble Space Telescope...
